OF NEW YORK, N. Y.

PROCESS 0F AND FURNACE FOR BURNING HYDROCARBON FLUIDS.

SPECIFICATION forming part of `Letters Patent No. 275,490, dated April 10, 1883.

Application filed June 1,1881.

To all whom it may concern Be it known that I, CHARLES HOLLAND, of the city, county, and State of New York, have invented certain new and useful Improvements inthe Process of and Furnaces for Burning Hydrocarbon Fluids; and I do hereby declare the following to be a sufficiently full, clear, and exact description thereof to enable others skilled in the art to make and use the said invention.

My invention' relates to that class of furnaces in which water or steam and iiuid hydrocarbons are introduced, volatilized, and burned with air, and 'has for its objects a greater durability ot' apparatus, greater cleanliness, ready adaptability to dierent forms and qualities of hydrocarbon iluids, and greater facility of control and regulation.

The invention consists in a wrought-metal retort containin ga horizontalpartition or shelf separatingthe hydrocarbon fluids from the steam or water, a superior form of such retort,

an improved air-inlet tube or pipe, and an imf proved method of regulating the supply of combustible matter to the different parts of the furnace.

I will now proceed to particularly describe.A

the mann-er in which the saidinvention is made and operated, referring in so doing to the drawings annexed and the letters of reference marked thereon.

Figure 1 represents a plan of my invention; Fig. 2, a vertical longitudinal section in the plane indicated by the dotted line or w in Fig. 1; Fig.l3, a transverse section in the plane indicated by the dotted line y y in Figs. 1 and 2; and Fig. 4 shows an enlarged view of thejetpipes or burners and airtubes.

The same letters of reference apply to the same parts inthe several figures.

A represents a retort, made of wroughtirou or steel, securely welded at all of the joints or seams, and having a horizontal partition or shelf, A', extending from the perpendicular end A2 of the retort toward, but not reaching, the upwardly-inclined or curved end A3. In

the end A2^ot` the retort, above the partition A', is the oil induct or supply pipe B, and below the partition A' in the end A2 is a water 5c or steam induet or supply pipe, C, and at the top of the upwardly-curved end A3 of the re- (No model.)

tort is inserted a discharge or outlet pipe, D

through which the products of distillation art;

nected branches and burners. Theseveral burners are surrounded by conical tubes F, through which air is admitted and directed upon the current of gaseous or vaporous fuel discharged from the burners E2. These tubes F are made of chilled cast-iron, this material being found to be of more satisfactorydurability than other metal, or than iron east without chilling.

The several sections of pipes E and retorts A are arranged in the furnace in a manner somewhat similar to that set forth in my LetL ters Patent numbered 239,7 85 and 239,786, and dated April 5, 1881, so that the retorts may be heated byjets ot' gaseous fuel burning under them before the supply of gaseous fuel is admitted to the entire furnace, and by opening the valves or gates E3 it maybe afterward admitted to the other burners in other parts ot the furnace.

The operation ot' the invention is as follows: Hydrocarbon fluid is admitted in a regulated supply at the pipe B to the chamber on the upper side of the partition A' in the retort A. and water or steam also admit-ted in regulated iiow by the pipe (l to the space in the retort A below the partition A'. The retort is heated primarily by a small quantity of 'oil burned in a priming-pan, as in the case of the furnaces described in my patents already referred to. Hydrocarbon vapors and gases and steam in superheated condition are deliveredby the pipe D from the upper end of the retort `A to the pipes E, and, escaping through burners Ehun" der the retort A, mingled with the air entering the tubes F, burn and produce a high temperature in the retort. The more volatile part of the hydrocarbon fluid is vaporized before reaching the end of the partition A', andthe less volatile portions, passing beyond the end of the partition A' and descending into the lower chamber of the retort A are then commingled or combined with the steam and ef- IOO fectuall y distilled therewith and converted into gaseous fuel, thus avoiding deposits ot' carbon or other solid or tarry residuum in the retort and completely utilizing the hydrocarbon.

Having described my invention, what I claim therein as new and as originally of my invention is- 1. The method of burning hydrocarbon fluids with steam and air, consisting in introducing such tiuid into a heated chamber, from which anyimperfectly-volatilized portions descend to a more highly-heated compartment, and after mingling or combining with steam therein are discharged to the burners in gaseous or vaporous form and burned with air, substantially as and with the eect set forth and described.

2. In an apparatus for burning hydrocarbons with steam and air, a retort ot wrought-iron or steel, having compartments partitioned from each other by a horizontal shelf, and intercom municating, substantially as and for the purpose set forth.

3. In an apparatus for burning hydrocarbons with steam and air, a system of distributingpipes provided with burners and arranged in sections intercommunicating by means ot' valves or gates, in combination with a retort or retorts so arranged and connected as to distill theliquid hydrocarbon, and heated by flame supplied from one or more of said sections, substantially as and for the purpose set forth.

4. In an apparatus for burning hydrocarbons with steam and air, the combination of the horizontallypartitioned retort A, supplied with steam or water and hydrocarbon duid, the outlet-pipe D, sectional pipes E, gates or valves E, branches E', and burners E2, substantially as and for the purpose set forth.

5. In an apparatus for burning hydrocarbons with steam and air, the combination of the partitioned retort A, supplied with steam or water and hydrocarbon Huid, the pipe D, and series of pipes E, provided with Valves E, and burners E2, with the air-tubes F, substantially as and for the purpose set forth.
